Environmentally Friendly Mold Remediation Techniques That Significantly Reduce Childhood Asthmaemanate from the bleached drywall or wood. Such odors even if veryfaint can be irritating to some sensitive people. See 9.10.Interior fiberglass-lined ductwork is also porous. If ductwork lining iscolonized by mold, cleaning alone cannot restore the lining to likenew condition.Under no conditions will it is permissible to spray any form ofpesticide or biocide into air ducts. This procedure is now prohibitedby the EPA, even though it is still widely performed.Disinfectants and cleaners used by AC duct cleaning firms are inalmost all cases designed to clean only hard surfaces such as AC coilsor other metal areas. These chemicals should not be used to attemptto clean or disinfect fiberglass supply and/or return air plenums.Contaminated fiberglass in an AC system or duct work must be replacedwith new or HEPA Vac'd and then painted with mold inhibitingencapsulant such as those produced by Foster or Design Polymericswhich are specifically designed for encapsulating HVAC ducting.There are NO chemical cleaners or disinfectants that are approved orwill be successful cleaning this highly porous material.See also the discussion under section 9.9 on Heating, Ventilation andAir Conditioning (HVAC) Systems.Porous materials without evidence of mold growth. Although notvisibly moldy themselves, many rough-surfaced porous materials mayalso become reservoirs of settled fungal particles if they have been nearheavy growth or high air concentrations. Examples include fiberglassduct board, upholstery, carpet, modular furniture, books, and files.These materials should be cleaned by careful HEPA vacuuming,laundering, or other methods that lift and capture fine dusts from thematerial’s surface.76
